To all whom it may c0ncern .1

Be it known. that I, OHARLns S. Goonme, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of h lassachusetts, have invented new and useful Improvements in Riveting-Machines, of which the following. is a specification.

This invention. relates to av machine for riveting pieces of sheet material together. In riveting two: pieces of sheet, material together there is oftentimes a. space between the adjacent surfaces; of the said-two pieces of sheet material beforethey are riveted which it is desirable to close up before the rivet is clenched. Moreover, in clenching a rivet it is desirable that the head of the rivet should be pressed against the outer surface of one of said pieces of sheet material before the clenching of the opposite end of the rivet against the face of the other piece ofsheet material begins. Otherwise, the rivet is liable to buckle between the end and the head and make an imperfect job in this respect, and also it will begin to clench as soon as it passes the outer surface of the under piece of material and make a very small curl over in the clenching operation.

In the machine of this invention the rivet.- ing operation is performedasfollows: The rivet is positioned in the holes designed therefor in the two pieces of sheet material. Said pieces of sheet material are then clamped firmly together, with the clenching end of the rivet projecting beyond the. lower surface of the sheet metal plate against which it is to be clenched and. while the parts are thus positioned an anvil is moved toward and into engagement with the projecting. end of said rivet, so that the entire amount of projection of the clenching end of the rivet shall be turned over or clenched against the face of the metal; plate after the rivet has been positioned in the plates and after the plates have been. clamped firmly together.

It is the object of this invention to provide a riveting machine which shall perform the riveting operation in the manner hereinbefore set forth, and in the present embodiment of my invention a stationary driver is employed and oppositely disposed to said driver is a movable work-support and a movable anvil. The rivet to: be illserted. in the sheet material is fed to a rivet carrier and. held therein while the worksupport' and anvil are, moved toward the driver.. The work-engaging surface of the wor "-support, is located in advance of the driver and after said work-support has: engaged the lower piece of sheet material and forced it up until. the rivet is: inserted in the holes in the metal plates and after the two pieces of material are clamped together, then the anvil continues its movement to ward the driver and. clenches. the projecting end of the rivet, against the surface of the plate adjacent to the anvil and work-support.

The invention consists in the combination and arrangement of parts set forth in. the

following specification and particularly pointed. out in. the claims thereof.

Referring to the. drawings: Figure 1 is a front elevation of my improved riveting machine. Fig- 2, is. a left hand side elevation of the same, Fig. 3 is a sectional elevation taken on line. 3-3 of Fig. 1.. Figs. 42,, 5 and 6 are detail, sectional elevations illustrating the relative positions of the parts during the. riveting operation.

Like numerals refer to like parts throughout the several views of the drawings.

In. the drawings, 10 is the frame of the machine, 11 is the driving shaft j ournaled to rotate in suitable bearings 12 and 13 in the frame of the machine.

14 is a pinion fastvv to.v the driving shaft and meshing into a gear 15 which is journaled to rotate upon a shaft 16 and forms one member of. a clutch 17 The other mem ber 18 of said. clutch is fastened to the shaft 16. The two -members. 15- and 18 are clutched together as one piece by suitable mechanism (not shown in the drawings, but well known to those s l'rilled. in the art), this mechanism being operated from. a treadle -(not shown in the drawings) by means of a treadle rod 19.

A driver 20 is held stationary in the frame 10 by a set-screw 21 and can be adjusted vertically by means of an adjusting screw 22 which bears against the upper end of the driver and has screw-threaded engagement with the frame 10. The rivets are fed. from a hopper 23. down a raceway 24 and are separated by a, slide 25 to be fed down a raceway 26 into a carrier 27 which consists of. two carrier blocks 28 and 29 fast to springs 30 and 31, respectively, said springs being fastened by a bolt 32 to a carrier slide 33.

The carrier 'slide 33 is guided in ways 34 formed in the frame of the machine. Said slide is normally held in the position illustrated in Fig. 2-that is, in its lowermost position, by a spring 35, one end of which is fastened to a pin 36 fast to the frame of the machine the other end of which is fastened to a pin 37 fast to said carrier slide. The lowermost position of the carrier slide 33 is regulated or adjusted by means of a stopscrew 38 which has screw-threaded engagement with the slide 33 and when the slide is in its lowermost position abuts against the frame 10.

The slide 25 is reciprocated to feed the rivets from the raceway 24 to the raceway 26 by a lever 39 pivoted at 40 to the frame 10. Said lever 39 has a rocking motion imparted thereto by a cam slide 41 which has a cam roll 42 rotatably mounted thereon and held against a cam 43 by a spring 44. The operation of the slide 25 in transferring the rivets from the raceway 24 to the raceway 26 is well known to those skilled in the art and, as it forms no part of this invention, requires no further description.

A movable work-support consisting of a sleeve 45 is slidably mounted upon an anvil 46 formed upon the upper end of a tube 47. Said tube is slidably mounted in the outer end of an arm 48 forming a part of the frame 10 and has a reclprocatory motion imparted thereto by toggle links 49 and 50 which are pivotally connected together and to a link 51 by a pin 52. The link 49 is pivotally connected at 53 to ears 54 extending downwardly from the lower end of the tube 47, while the link 50 is pivotally connected at 55 to arms 56 rigidly fastened to the outer end of the arm 48 and extending downwardly therefrom.

The link 51 is made in two parts joined together by a turn-buckle 57 and is connected at its rear end by a pin 58 to a lever 59 pivoted at 60 to the frame of the machine.

The lever 59 is connected by a pin 61 to a crank-rod 62 which is connected by a crankpin 63 to the cam 43. A collar 64 is fastened to the tube 47 by a set-screw 65 and between said collar and the work-supporting sleeve 45 there is interposed a spring 66. Within the tube 47 is inclosed a spring 67, the upper end of which bears against a collar 69 which is fastened to a guide-pin 70 slidable vertically in the anvil 46; the lower end of said spring bears against a pin 68. The pin 68 is adjustably supported upon a screw 71 having screw-threaded engagement with the lower end of the tube 47. A pin 72 is fastened to the tube 47 and projects laterally therefrom through a slot 73 provided in the work-supporting sleeve 45. By

rotating the turn-buckle 57 in the proper direction the tube 47, with the anvil 46, can be raised or lowered to bring the same 'nearer to or farther from the upper surface of the work-support 45 and also nearer to or farther from the driver 20. Normally the upper surface 74 of the work-support 45 is located above the upper surface of the anvil 46 and between said anvil and the lower end of the driver 20. The rivets used in this embodiment of my invention are tubular rivets and the operation of riveting is illustrated in three steps in Figs. 4, 5 and 6. As hereinbefore set forth the rivets descend the raceway 26 and enter a chamber or pocket 75 located between the carrier blocks 28 and 29. The work, consisting of a plurality of plates of sheet metal 76 and 77 which are to be riveted together, is placed upon the work-support 45 in the position illustrated in Fig. 4, with the upper surface of the plate 77 resting against the upper surface of the movable work-support 45. In this position of the parts it will be seen that the work-en gaging surface of the worksupport lies in a plane between the driver 20 and the work-engaging surface of the anvil 46. The guide-pin 70 at that time projects through the two layers of sheet material 76 and 77.

The tubular rivet 78 is held in the pocket 75 of the carrier 27 and when the clutch of the machine is thrown into operation the the toggle links 49 and 50, the link 51, lever 59 and crank-rod 62. Upon a continued upward movement of the anvil and worksupport the parts assume the positions illustrated in Fig. 5, the guide-pin 70 having entered the bore of the tubular rivet and the carrier having been moved upwardly until the head of the rivet 78 abuts against the lower end of the driver 20. The plates 76 and 77 will then be clamped firmly together and the parts held in the relative positions illustrated in Fig. 5, with the carrier blocks 28 and 29 spread apart, the under side of the head of the rivet resting against the upper surface of the plate 76 and the lower end of the rivet projecting through and beyond the lower surface of the plate 77. Now, the work-support cannot move-upwardly any farther and upon a continued upward movement of the anvil 46 the spring 66 will yield and allow the anvil to engage the projecting lower end of the rivet 78 and curl the same over against the under surface of the plate 77.

The ope 'ation of riveting now being com pletecl the tube 47 will be moved down"- wardly, together with the anvil 46 and the work-support 45, until the parts assume the relative positions illustrated in} Fig; 3. The operator will then move the plates to insert therein in a new hole the upper end or the guide-pin as before and the operation hereinbefore described for feeding, positioning and setting a new rivet in the plates will be repeated. I

While in the foregoing description and in the drawings an embodiment of my invention is described and illustrated particularly adapted to handle and set tubular rivets, I do not wish to be understood as limiting my invention to the use of tubular rivets, as with very slight modifications Within the knowledge of one skilled in the art other forms of rivets can be used, fed and clenched without departing from the spirit of my invention,
